wherein R1 and R2, which may be the same or different, each represents a straight-chain or branched-chain alkylradical of 2.to 6 carbon atoms, or a cyclohexyl, alkoxyalkyl or hydroxyalkyl radical, and X represents a hydrocarbon radical having up to 4 carbon atoms which may be substituted by a methyl group;
a compound of formula (II):
wherein
X2 is sulphur and Y is oxygen or sulphur:
R4 is an alkyl group of up to 6 carbon atoms;
R5 is an alkyl group of up to 6 carbon atoms; and m is 1; or
